I too, have a Mac and use Firefox. I also use my AOL, Safari, Opera, etc. browsers.

I'll try again to explain: I'm in eBay and didn't directly go to PayPal, rather eBay has transferred me there to pay for the auction. After I am back in eBay, I'm still the same tab with nothing to show that I'm in PayPal. If I go to another tab, and type in www.paypal.com, it will bring me back to PayPal, where I am still logged in. No clicking on history or using the back button is involved.

That never happened in the past where, once I was back to eBay, I'd have to log on again to PayPal to go back there. Hope I explained it a little better.
